precompile

Supports precompiling binaries for usage on the scrimmage server.

Usage guide:

0. Make sure that you have docker installed on your machine for command line usage https://docs.docker.com/install/

   Docker on Windows Subsystem for Linux (WSL) requires a special installation (Google is your friend).

   Also make sure that you have make installed on your command line environment:

   $ make --version

   should not fail.

1. Clone this repository into a convenient working directory.

2. Create a subdirectory named scrimmage which contains a working engine game you would like to use to precompile your code. scrimmage should contain engine.py and config.py, as well as pokerbot(s) to play a game against each other (or the same pokerbot against itself, described in config.py).

3. Run

   $ make prebuild

   in this directory. The first run will be very slow in order to download all the dependencies, but subsequent runs will cache the results to speed it up. Alternatively, you may delete dependencies you do not need to speed up the first run.

   The above command will create a directory called built which contains the prebuilt pokerbot.

   Run

   $ make clean

   in this directory to prep the directory for another pokerbot precompilation.

4. Change commands.json in the built directory to have no build command:

   "build": [],

5. Zip your pokerbot and upload it to the scrimmage server.

Note: There is a bug within python's unzip utility: python/cpython#17790

As a workaround, you should have your build command be a python program which sets the correct file permissions for your compiled program.

commands.json:

{
    "build": ["python3.7", "permissions.py"],
    "run": ["./cppbot"]
}

permissions.py:

import os

os.system("chmod +x ./cppbot")
